Application filed March 23, 1900. Serial No. 9.879. (No model.) i

Tox ,all whom, it may concern:

Be it known that I, ARTHUR A. HAMER- SCHLAG, a citizen of the UnitedStates, residing in the city, county,and State of New York, haveinvented certain new and useful Improvements in Motor-Vehicles, of whichthe following is a specification.

This invention relates to improvements in motor-vehicles,andparticularly to a tractiontruck adapted to be substituted for or inplace of the forward-wheel truck of an ordinary four-wheeled vehicle, soas to convert such vehicle into a self-propelling vehicle without makingany other change in the vehicle itself.

The special objects of the present invention are to facilitate theattachment of the traction truck to the vehicle, to minimize the amountof alteration required in the vehicle-body, and to provide for theoperation, steering, and control of the traction-truck in a simple andadvantageous manner.

In the accompanying drawings, Figure 1 is a side elevation of a vehiclewith my improved traction-truck applied thereto. Fig. 2 is a verticalsection of the traction-truck on the line A A in Fig. 3. Fig. 3 isahorizontal section 'on the line B B in Fig. 2. horizontal detailsection on the line C C in Fig. 2, showing the actuating devices for thesteeringgear. Fig. 5 is a vertical section of said actuating devices.Figs. 6 to 8 show modications.

Referring to Fig. 1, the body or frame ofa vehicle (represented at 1) isconnected by a king-pin connection with the traction device forming thesubject of the invention. The said traction device comprisestraction-wheels 2 2, whose shafts 3 3 in Fig. 3 are journaled insuitable bearin gs in the frame 4 of the traction device. In the centerof the traction device and extending upwardly is a tubular post orstandard 5, which, together with a fifth-wheel plate G, is attached tothe body 1 of the vehicle yand is adapted to turn on the frame of thetraction device,said post 5 extending through an opening in the iioorofthe vehicle-body and into convenient proximity to the drivers seat. Thispost serves as the king-pin connection between the tractiontruck frame 4and the vehicle-body 1, and it also serves to contain the lvarioussteering and controlling instrumentalities, which at Fig. 41sa the upperpart of this post are provided with manual actuating devices,while attheir lower ends they are in mechanical connection with the severalcontrolling and steering devices on the truck. All the controlling andsteering connections between the Vehicle and the traction-truck beinglocated within this 'pivotal center post or king-pin connection, thedisturbance of the iioor of the vehicle is reduced to a minimum and thetruck is enabled to swing entirely around on its center, giving theutmost freedom in steering and backing. The lever 7 in Fig. 1 is` theusual hand-brake lever and has no connection with the traction-truck.

The traction-truck is shown more in detail in Figs. 2 to 5, whereinthemotor S is shown as mounted on the frame 4 and connected by gearingwith the truck-shafts 3 3. The motor here shown is a gas-engine of anysuitable type, and in order to enable it to run continuously in the samedirection while the vehicle is being run forward or backward I prefer toemploy a reversing-gear, consisting, for example, of bevel-Wheels 10 10,carried by counter-shafts 11 11 and engaging on opposite sides of abevel-gear 12 on a shaft 13, geared by bevel-wheels 14 14 to theV mainshaft 15 of the gas-engine. Friction-clutches 16 16, connected with therespective bevelwheels 10 10, enable either one or the other of suchbevel-Wheels to be clutched to the corresponding shaft 11, according asthe movable members of such clutches are thrown one Way or the otherlongitudinally on said shaft.

wise to the shafts 3 3 of the respective tracV` tion-wheels, adifferential gear being preferably interposed, as indicated at 24, inthe connection to one of the truck-shafts to en- ICO able the vehicle toturn curves more readily and equalize the operation of the truck-Wheels.

25 represents a spindle governing the admission of air and fuel, or ofeither of them, to the gas-motor in any suitable and usual manner, and26 is a shiftable device controlling the point of ignition. In startingit is generally desirable to shift the point of ignition forward andthen shift it back again after the engine is Well started. Such Valvemechanism and ignition-controlling devices being well known in the artt-hey are not herein shown in detail. y

The fifth-Wheel plate 6, which is attached to the tubular king-pin post5 by means of spokes or ribs 27, is secured to the bottom of thevehicle-body, as shown in Fig. 1, by means of suitable fastenings 28, sothat said king-pin post and the fifth-wheel plate turn with thevehicle-body. The central part of the top of frame 4 is made in the formof an open frame or spider 29, carrying a central hub or journal-bearing30, wherein the tubular king-post 5 turns, and the fifth-,Wheel plate Galso bears on the top of frame 4 by a ball-bearing 3l, this ball-bearing being made in the top of a ring 32, formed at the top of frame 4. Theinner side of this ring 32 is toothed and serves as a steering-gear ringfor the traction-truck. A pinion 33, engaging with this steering-gearring, is connected by gearing, such as shafts 34 35 36 and bevel- Wheels37 38, (see Figs. 2, 4, and 5,) With a pinion 39, that engages with aninternal gearring 40 on ythe collar or hub 41 of a hand- Wheel or manualactuating device 42, mounted at the top of thetubular king-pin post 5,the said collar or hub 4l being adapted both to turn and to slidevertically in said tubular post, which serves as a journal-bearing andguide therefor. The hand-wheel 42 normally rests by gravity on the topedge of the tubular post 5, and in this position (shown in Fig. 2) theinternal gear 40 is in engagement with the pinion 39, so that rotationof the hand-Wheel will actuate the steering-gear connections 38 37 33and turn the steeringgear ring 32 so as to turn the traction-truckrelatively to the vehicle-body.

Starting mechanism for starting or turning over the motor by hand isalso provided, the same comprising a bevel-gear 43 on thetransmitting-shaft 13, above referred to, engaging with a bevel-gear 44,journaled on a stud and carrying a similar gear 46 rigidly attached toit. A starting rod or spindle 47 is mounted centrally in the tubularking-post and carries at its lower end a bevel-Wheel 48, which engageswith said bevel-gear 46. The rod 47 turns loosely in a tubular spindle49, which is rotatably supported in the central hub or bearing 30, andsaid rod 47 carries at its upper end a head 50, provided with anoffsetslot 51, adapted to engage with a pin 52 on the inside of the hub ofhand-wheel 42 when said hand-Wheel is raised. By raising the hand-Wheel42 and turning it to the right the pin 52 is carried into the oset ofslot 51,- and the hand-Wheel is thus locked in its raised position inengagement with the starting-rod and with its gear-ring 40 out of engagement with the steering mechanism. On then continuing to turn thehand-Wheel the' rod 47 and bevel-gears 46 45 44 43 transmit motion tothe motor-gearing. A spring friction-paWl 53 prevents accidentaldisplacement of the hand-wheel. After the engine has been started thispawl is released by its finger-piece and the hand-Wheel is turned backand dropped to its lower position, thus bringing the steering-gear againinto connection. Y

The sleeve or tubular spindle 49, surrounding the rod 47, carries at itsupper end an actuating-handle 54, projecting through a slot 55 in theside of the vtubular post 5, said tubular spindle 49 being provided atits lower end with an arm 56, engaging by a pin-andslot connection withone of the clutch-operating levers 17, so that by moving the handle 54sidewise in the slot 55 the revers- 8on 'Y 'Y ing and disengagingclutches are thrown into vthrough the central king-pin post 5.

The several handles and hand-Wheels or manual actuating devices 42 50 5457 58 are preferably made detachable from the parts they actuate, sothat on removing them the vehicle-bod y, with the attached king-pin postand fifth-wheel plate, may be lifted bodily o the truck-fra me 4, areverse proceeding being carried out in assembling. The gasolene- 4andis connected by pipe 68 to the .admission devices of the gas-motor.

truck and the vehicle-body.

The construction of the transmitting mechanism in the king-pin post forthe startinggear, steering-gear, the., may be varied, as shown in Fig.6, Where all 'the said transmitting members are shown asconcentricallyarranged sleeves or spindles Working within the tubularpost 5 and around the central rod if 62, the latter in this casecontrolling lthe igniting mechanism. The sleeve 47, directly surroundingthe said rod, carries at its lower end the bevel-gear 48 for startingthe motor,

This location of the said reservoir also conduces to the ease ofassembly and separation of the traction-V and the successive sleeves 49and lrcontrol, Y

respectively, the clutch and the valve-gear.

7s Y Y,

j f reservoir 67 is also located in the truck-frame 1 The outermostsleeve or spindle 41 is formed as a downward extension of or is attachedto the hand-Wheel 42 and is provided at its lower end with gear-teeth40, connected through idlers 68 69 With a pinion 70,pivotedin thefifthwheel frame 6, and rigidly connected to the pinion 33, engaging inthe steering-gear ring 32 on the traction-truck frame 4.

The several concentric spindles 62, 47, 49, 61, and 41 are respectivelyprovided at their upper ends with handles or actuating devices 58, 7 :2,54, 57, and 42, arranged in descending order, so that each may be turnedindependently of the others.

Fig. 7 shows the application of chain-gearing carrying chain 7 3 andsprocket-Wheels 74 75 76 in place of the bevel-Wheels and shaft 1-5 fortransmission from the motor to the clutch-shaft. In this case thereversal is effected by the interposition of an idler 77 on one sidebetween the gears 2O 2l, so as to reverse the motor when the clutches 16are on them to bring that side into operation. The starting bevel-gear48 in this case engages bevel-gear 46, formed on the side ofintermediate sprocket-Wheel 75.

In Fig. 8 the transmitting connection` from the motor to the clutches isby spur-gearing 74 75 76, the operation being otherwise the same as inFig. 7, with the exception that the motor 8 is here shown as an electricmotor provided with a regulating-rheostat 78 and a supply storagebattery 79, with controllingswitch 80, said rheostat and switch beingcontrolled, respectively, by levers 8l 82, connected by links 83 84,respectively, to the operating-rods 61 62, located in and extending upthrough the tubular king-pin post above described. In this case, as inthe others, the supply of operating medium for the motor is carried bythe traction-frame itself, so that there is no necessity of sliding orextensible connections between the truck and the vehicle. I have shownstarting and reversing mechanism in this case also, as the use of suchdevices in connection with an electric motor, while not absolutelynecessary, is of advantage in that it enables the operator to save thestorage battery from excessive load in starting and in reversing.
